Overview
Diagnostic Study of Choice
- Echocardiography is the gold standard test for the diagnosis of cyanotic congenital heart diseases.[1]
Diagnostic Criteria
- The diagnosis of cyanosis is made when the following diagnostic criteria are met:
- Transient bluish discoloration of hands and feet in the neonate or acrocyanosis
- Response to oxygen therapy in peripheral cyanosis
- NO response to oxygen therapy in central cyanosis
- Discoloration of hands and feet in peripheral cyanosis
- Discoloration of mucous membrane and lips in central cyanosis
- The diagnosis of central cyanosis in the neonate is made when at least one of the following diagnostic criteria are met:
- Insufficient pulmonary oxygen intake such as respiratory failure, upper airway obstruction, hypoventilation
- Insufficient pulmonary blood flow such as increased pulmonary vascular resistance, congenital heart disease
- Unusual pattern of pulmonary blood flow such as transposition of great arteries (TGA), total anomalous pulmonary venous connection (TAPVC), pulmonary arteriovenous malformation
